This topic describes how to update the minor engine version of an ApsaraDB RDS for PostgreSQL instance. You can manually update the minor engine version of your RDS instance to improve database performance, use new features, and fix bugs.

Prerequisites

Your RDS instance uses standard or enhanced solid-state drives (SSDs).
Note If your RDS instance uses local SSDs, you cannot manually update the minor engine version of the instance. In this case, you can restart your RDS instance. During the restart process, ApsaraDB RDS updates your RDS instance to the latest minor engine version. For more information, see Restart an ApsaraDB RDS for PostgreSQL instance.

For more information about the features that are supported by different minor engine versions, see Release notes of minor AliPG versions.

Precautions

  • When you update the minor engine version of your RDS instance, the instance may encounter a transient connection of about 30 seconds. We recommend that you update the minor engine version during off-peak hours. Alternatively, make sure that your application is configured to automatically reconnect to your RDS instance.
  • After you update the minor engine version of your RDS instance, you cannot downgrade the instance to the previously used version.
  • When you perform operations such as upgrading your RDS instance, ApsaraDB RDS updates the instance to the latest minor engine version.
